Copper ions flow like liquid through crystalline structures

Materials scientists have sussed out the physical phenomenon underlying the promising electrical properties of a class of materials called superionic crystals through the investigation of CuCrSe2. A better understanding of such materials could lead to safer and more efficient rechargeable batteries than the current standard-bearer of lithium ion. https://www.sciencedaily.com/releases/2018/10/181008114613.htm
